Description

This application claims priority from Chinese Patent Application No. 201810032716.8 filed with the Chinese Patent Office on Jan. 12, 2018, the entire content of which is incorporated herein by reference.
TECHNICAL FIELD The present disclosure relates to the field of communication technology, and more particularly to a UE capability reporting method, slot offset determination method and apparatus.

In the TS38.214 protocol of the 5G (5th-Generation) mobile communication system, if one CSI resource set (CSI resource set) is set for UE (User Equipment), the CSI reference on the time domain of one serving cell A resource (CSI reference resource) is defined as a downlink slot _{nn CQI_ref} (where n is the slot reporting CSI from the UE to the network equipment and n _{CQI_ref} is the slot offset).

Also, if the CSI reported from the UE is periodic and semi-persistent CSI reporting, n _{CQI_ref} is the minimum value greater than or equal to T1 and corresponds to one valid downlink slot. If the CSI reported from the UE is an aperiodic CSI report, and the network device instructs the UE to report CSI in the same slot of the CSI request (CSI request) using DCI (Downlink Control Information), n _{CQI_ref} is 0. Otherwise, n _{CQI_ref} is the minimum value greater than or equal to T2 and corresponds to one valid downlink slot.

For convenience of explanation, T1 and T2 may be referred to as the reference slot offset T of the CSI reference resource.

Apparently, the described embodiments are some but not all of the embodiments of the present application. Based on the embodiments of the present application, all other embodiments that a person skilled in the art can do without creative work shall fall within the protection scope of the present disclosure.

The technical means of the embodiments of the present disclosure are, for example, the GSM (Global System of Mobile communication) system, the CDMA (Code Division Multiple Access) system, the WCDMA (Wideband Code Division Multiple Access) system, the GPRS (General Latency Pad) system, （Ｌｏｎｇ Ｔｅｒｍ Ｅｖｏｌｕｔｉｏｎ）システム、ＬＴＥ ＦＤＤ（Ｆｒｅｑｕｅｎｃｙ Ｄｉｖｉｓｉｏｎ Ｄｕｐｌｅｘ）システム、ＬＴＥ ＴＤＤ（Ｔｉｍｅ Ｄｉｖｉｓｉｏｎ Ｄｕｐｌｅｘ）、ＵＭＴＳ（Ｕｎｉｖｅｒｓａｌ Ｍｏｂｉｌｅ Ｔｅｌｅｃｏｍｍｕｎｉｃａｔｉｏｎ Ｓｙｓｔｅｍ）又はＷｉＭＡＸ（Ｗｏｒｌｄｗｉｄｅ Ｉｎｔｅｒｏｐｅｒａｂｉｌｉｔｙ ｆｏｒ Ｍｉｃｒｏｗａｖｅ Ａｃｃｅｓｓ）通信システム、５Ｇシステム、又はＮＲ（Ｎｅｗ It should be understood that it is applicable to a variety of communication systems, such as Radio systems.

A User Equipment (UE), also called Mobile Terminal, Mobile Terminal Equipment, etc., can communicate with one or more core networks via a radio access network (eg, a Radio Access Network (RAN)). Terminal equipment is a mobile terminal, such as a mobile phone (also called a "cellular" phone), and a computer with a mobile terminal, e.g. Yes, exchanging language and/or data with the radio access network.

A network equipment is a device deployed in a radio access network equipment to provide wireless communication functions to terminal equipment. The network equipment may be a base station. The base station may be a GSM or CDMA base station (BTS (Base Transceiver Station)), a WCDMA base station (NodeB), an LTE evolved base station (eNB or e-NodeB , evolutionary Node B) and 5G base stations (gNB).

Hereinafter, technical means of each embodiment of the present disclosure will be described in detail based on the drawings.

FIG. 1 illustrates a UE capability reporting method according to one embodiment of the present disclosure. As shown in Figure 1, this UE capability reporting method includes a step 101 of reporting CSI calculation related capabilities to network equipment.

Here, the CSI calculation related capabilities are at least in different numerologies of CSI report types supported by the terminal equipment, the maximum number of CSI reports supported by the terminal equipment, and different numerologies of the CSI report types supported by the terminal equipment. It includes one or more combinations of CSI computation time corresponding to one CSI computation complexity level and an identifier of a list of CSI computation times supported by the terminal equipment.

More specifically, the CSI report types supported by the terminal equipment include the report content types supported by the terminal equipment, the codebook types used, and so on. That is, the CSI report types supported by the terminal equipment can be distinguished based on the report content types supported by the terminal equipment and the codebook types used.

For example, the CSI report types are CRI/RI/PMI/CQI, CRI/RI/i1, CRI/RI/i1/CQI, CRI/RI/CQI, CRI, CRI/RSRP, CRI/RI/SLI/ It is classified into types such as PMI/CQI. If a CSI report includes a PMI report, the CSI report type may be classified into types such as Type-I or Type-II based on the codebook type used.

Here, CRI is CSI-RS Resource Indicator and CSI-RS is CSI reference signal. RI is a Rank Indicator. CQI is a Channel Quality Indicator. PMI is a precoding matrix indicator (Precoding MatrixIndicator). SLI is the StrongestLayerIndicator. RSRP is reference signal received power (Reference Signal Received Power). i1 is the first level codebook indication.

Of course, the CSI reporting types supported by the terminal equipment may be classified according to the CSI computational complexity level and numerology, to which the embodiments of the present disclosure are not limited.

Numerology is identified based on BWP (BandWidth Part) information accompanying CSI report request information (CSI request), specifically by SCS (SubCarrier Spacing) and CP (Cyclic Prefix) accompanying in CSI report request information identified. Here, SCS is, for example, 15 KHz, 30 KHz, 60 KHz, 120 KHz.

Here, for periodic CSI (Periodic CSI) reporting, the CSI report request information may be set by RRC (Radio Resource Control) signaling ReportConfig. Semi-Persistent CSI reporting may be activated by Downlink Control Information (DCI). Aperiodic CSI (Aperiodic CSI) reporting may be triggered by DCI. The terminal equipment can obtain the information of CSI reporting required by the network equipment, including periodicity, CSI reporting type and codebook type used, etc. from the CSI reporting request information.

Multiple CSI reports in the terminal equipment (may be multiple types or multiple CSI computational complexity levels or multiple CSI reports with multiple numerologies, or multiple CSI reports with the same CSI report type ) at the same time, the CSI calculation time corresponding to at least one CSI calculation complexity level in different numerologies of CSI report types supported by the terminal device is at least CSI computation time corresponding to one CSI computation complexity level.

It is understood that the CSI computation time is the number of OFDM symbols required to compute and obtain the CSI report. The length of CSI computation time reflects the CSI computation complexity. In general, a longer CSI calculation time indicates a higher level of CSI calculation complexity, while a shorter CSI calculation time indicates a lower level of CSI calculation complexity.

The identifier of the CSI calculation time list supported by the terminal equipment is the identifier of the CSI calculation time list set by the manufacturer of the terminal equipment when the terminal equipment is shipped. A standard or protocol can define a plurality of CSI calculation time lists, such as Table 1, corresponding to the capabilities of different terminal equipment. Thereby, the manufacturer of the terminal equipment sets the identifier of the CSI calculation time list supported by the terminal equipment according to the capability of the manufactured terminal equipment. Further, when receiving from the terminal equipment an identifier of a CSI calculation time list supported by this terminal equipment, the network equipment complies with this identifier and selects this terminal equipment from a plurality of CSI calculation time lists defined in standards or protocols. can identify a list of CSI calculation times supported by , and identify the CSI calculation time when this terminal generates a corresponding CSI report.

Optionally, said CSI computation related capabilities are:
CSI information belonging to multiple CCs (Component Carriers) and corresponding CSI calculation complexity levels and CSI calculation times in numerology, which can be updated simultaneously by terminal equipment;
It further includes one or more combinations of different CSI report types, or CSI report combination information in CSI calculation complexity level and numerology and corresponding CSI calculation time, which can be updated simultaneously by the terminal equipment.

Here, the CSI information belonging to a plurality of CCs that can be simultaneously updated by the terminal device includes the maximum number of CCs that can be updated simultaneously, information about the CC itself that can be updated simultaneously, and the like.

CSI report combination information of different CSI report types or CSI computational complexity levels that can be updated simultaneously by the terminal equipment, various possible CSI combinations of different CSI report types that can be updated simultaneously by the terminal equipment, each CSI It includes the number of CCs that the terminal equipment can support in combination, the maximum number of CCs that the terminal equipment can support, and the like. For example, one CSI combination information is the Type-II codebook type CSI in the first CC of simultaneous update, the Type-I codebook type in other multiple CCs, and the CCs that the terminal equipment can support in this combination. including the number of Further, for example, a CSI combination that can be simultaneously updated by a terminal device is one Type-II codebook type CSI and a plurality of Type-I codebook type CSIs. Or, for example, a CSI combination that can be updated simultaneously by a terminal device is two Type-II codebook type CSIs and multiple Type-I codebook type CSIs.

Since the computational complexity may differ depending on the type of CSI and the processing capability may vary depending on the terminal device, even if each terminal device calculates the same type of CSI, the calculation time required for each terminal device is They are not necessarily the same, that is, the CSI calculation capabilities of each terminal device may differ.

Prior art network equipment does not take into account the CSI computation capability of each terminal equipment, but in the embodiments of the present disclosure, for a given numerology and CSI computation complexity level, only SCI is used in the Physical Uplink Shared Channel (PUSCH). (not including data) is transmitted, taking an aperiodic CSI reporting trigger as an example, receiving a DCI containing a CSI reporting trigger indication, PDCCH (Physical Downlink Control Channel) detection decoding, channel estimation and CSI calculation The CSI calculation time Z is specified mainly with reference to the minimum number of OFDM symbols required for . These factors reflect the terminal equipment's CSI calculation-related capabilities and may enable the terminal equipment to report CSI reports to the network equipment in a more timely manner.

A UE capability reporting method according to embodiments of the present disclosure can report CSI computation-related capabilities to network equipment. As such, the network equipment can request CSI reporting from the terminal equipment based on the actual capabilities of the terminal equipment. This not only increases the flexibility of the network equipment to set the CSI requirements to the terminal equipment, but also allows the terminal equipment to adapt the time for calculating the CSI to its own computing power. This allows the terminal device to report the CSI report to the network device at a more appropriate timing, without causing waste of time domain resources, and also prevents the lack of computation time to report the updated CSI report to the network device. It is possible to improve the efficiency of the terminal device feeding back the CSI report.

FIG. 2A illustrates a slot offset determination method of one embodiment of the present disclosure. This method is also applied to terminal equipment. As shown in FIG. 2A, the method includes the following steps.

In step 201, receive CSI reporting request information sent from a network device.

Generally, the CSI request information (CSI request) sent from the network equipment includes information such as the number of CSI reports, the type of each CSI report, the codebook type that the terminal equipment is expected to use, and the CSI reporting bandwidth. including. The terminal device can specify the CSI calculation time from these pieces of information.

At step 202, a reference slot offset T is determined based on the CSI report request information.

In one specific embodiment, prior to step 202, the method further comprises receiving a preset reference slot offset T by the network equipment. Then, step 202 specifically identifies a target CSI report that needs to be reported according to the CSI report request information, and presets a reference slot offset T matching the target CSI report by the network device. and determining among the reference slot offsets T that have been determined.

In another specific embodiment, step 202 specifically identifies a CSI calculation time for a CSI report based on said CSI report request information, and identifies a reference slot offset T based on said CSI calculation time. including doing.

Here, identifying the CSI calculation time of the CSI report based on the CSI report request information includes first identifying the numerology and CSI calculation complexity level corresponding to the CSI report based on the CSI report request information, Then, identifying a CSI computation time for the CSI report at said numerology and said CSI computation complexity level.

More specifically, determining the CSI computation time Z of the CSI report at the numerology and the CSI computation complexity level is specifically determined by any one of the following three schemes.

Method 1: Determine the CSI calculation time Z of the CSI report in the numerology and the CSI calculation complexity level according to the CSI calculation-related capabilities of the terminal equipment.

The specific contents of the CSI calculation-related capabilities of the terminal equipment are consistent with the description of the embodiment shown in FIG. 1, and will not be repeated here to avoid duplication.

Method 2: Receive the CSI calculation time Z of the CSI report at the numerology and the CSI calculation complexity level previously signaled by the network device.

Specifically, receive the CSI calculation time Z of the CSI report at the numerology and the CSI calculation complexity level previously set by the network equipment through DCI signaling.

Method 3: Identify the CSI computation time Z of the CSI report in the numerology and the CSI computation complexity level according to a predetermined CSI computation time list.

The predetermined CSI calculation time list is a CSI time specific list defined according to conventional protocols. The CSI time specific list defined in the protocol is shown in Table 1.

In Table 1, CSI computation times Z corresponding to different CSI computation complexity levels and subcarrier spacings SCS are defined, where the unit of Z is OFDM symbol. In Table 1, any subcarrier spacing SCS corresponds to one low complexity 1 CSI computation time Z, and no specific application scenario is specified. This application scenario is, for example, a Type-I codebook type scenario with up to 2-port CSI-RS or a scenario without PMI feedback with up to 8-port CSI-RS. Any subcarrier spacing SCS corresponds to one high-complexity CSI computation time Z, and no specific application scenario is specified.

Each CSI calculation complexity level and the CSI calculation time Z at the subcarrier spacing SCS shown in Table 1 above are the minimum requirements to be met by the terminal equipment, that is, the criteria to be met by all terminal equipment. Of course, the CSI calculation time Z at each CSI calculation complexity level and subcarrier spacing SCS may be smaller than the corresponding values in Table 1 if the terminal equipment itself has relatively large calculation capability. Alternatively, the protocol may define multiple tables with different Z values, corresponding to UEs with different computing capabilities.

Specifically, the ratio of the CSI calculation time and the number of OFDM symbols included in one slot is specified, the ratio is rounded up to obtain an integer, and the integer is specified as the reference slot offset T.

That is, the reference slot offset T can be specified by Equation 1 below.

formula 1

where Z is the CSI calculation time specified in step S202 and _NsymbSlot is the number of OFDM symbols included in one ^slot ;

indicates rounding up.

If the CSI report identified based on the CSI report request information is a periodic or semi-persistent CSI report, in step 203 above, the reference slot offset T identified based on the CSI calculation time is the first reference slot. offset T1. The CSI report identified based on the CSI report request information is an aperiodic CSI report, and the CSI reporting slot indicated by the DCI by the network device and the slot in which the DCI including the CSI request information exists are the same slot. Otherwise, in step 203 above, the reference slot offset T identified based on the CSI calculation time is a second reference slot offset T2.

The meanings of T1 and T2 are not repeated here to avoid duplication, see the background art of this disclosure for details.

Note that T1 and T2 may be the same or different in the embodiments of the present disclosure. Of course, T1 and T2 may be set by the network equipment in RRC signaling ReportConfig. It can be appreciated that the network equipment can specifically configure multiple T1s or T2s, respectively, for different types of CSI reporting required.

In step 203, a slot offset of a CSI reference resource is determined based on the reference slot offset T;

The slot offset of the CSI reference resource is n _{CQI_ref} described in the background art of this disclosure. In order to clearly understand the technical means according to this embodiment, the process of the slot offset n _{CQI_ref} of the CSI reference resource will be described again below.

If the CSI that needs to be reported from the terminal equipment is periodic CSI reporting and semi-persistent CSI reporting, n _{CQI_ref} is the minimum value greater than or equal to T1 and corresponds to one valid downlink slot. That is, when the CSI that needs to be reported from the terminal device is a periodic CSI report and a semi-persistent CSI report, the valid downlink slot closest to T1 from among the slots equal to or greater than T1 is selected as the slot offset of the CSI reference resource. n Select as _{CQI_ref} . Furthermore, the n _{CQI_ref} -th slot immediately before the CSI reporting slot n is set as a CSI reference resource.

If the CSI reported from the UE is an aperiodic CSI report, the network device instructs the UE to report CSI in the same slot of the CSI request information (CSI request) using DCI (Downlink Control Information), n _{CQI_ref} is zero. Otherwise, n _{CQI_ref} is the minimum value greater than or equal to T2 and corresponds to one valid downlink slot. That is, among slots equal to or greater than T2, a valid downlink slot closest to T2 is selected as the slot offset n _{CQI_ref} of the CSI reference resource. Furthermore, the n _{CQI_ref} -th slot immediately before the CSI reporting slot n is set as a CSI reference resource.

Here, a valid downlink slot means that the slot is a downlink slot for the UE, the slot is not in the measurement gap configured for the UE, and the downlink bandwidth part (BWP) of the slot is CSI Refers to a slot that satisfies the condition that it matches the downstream BWP corresponding to the report.

The slot offset identification method according to the embodiment of the present disclosure can identify the specific value of the reference slot offset T (specifically T1 or T2) based on the CSI report request information, so that the existing TS38. H.214 protocol does not explicitly define T1 and T2, and without reference to LTE systems defining constant T1 and T2 values to specify the slot offset n _{CQI_ref} of the CSI reference resource. good. This makes the slot offset n _{CQI_ref} of the CSI reference resource specified by the embodiments of the present disclosure more flexible and matches the terminal equipment's own CSI calculation capability.

In addition, in step 202, if the CSI calculation time of the CSI report at the numerology and the CSI calculation complexity level is specified based on the CSI calculation related capability of the terminal device, the slot offset n of the specified CSI reference resource is determined. _{CQI_ref} can be better matched to the CSI calculation capability of the terminal equipment itself, so that the terminal equipment can timely report the CSI report to the network equipment, and waste time domain resources can be eliminated; It can be seen that there is no shortage of computation time to fail to report the updated CSI report to the network equipment, and the efficiency of feedback of the CSI report by the terminal equipment is improved.

Optionally, in other embodiments of the present disclosure, the CSI report request information indicates that there are multiple CSI reports, and the number of reference slot offsets T specified based on the CSI calculation times of the multiple CSI reports is If there is more than one, the above step 203 specifically includes identifying the slot offset of the CSI reference resource according to the maximum value of the identified multiple reference slot offsets T;

Optionally, in other embodiments of the present disclosure, step 203 above specifically includes determining at least two CSI reference resources based on different reference slot offsets T among the identified plurality of reference slot offsets T. Including specifying the slot offset. For example, the network equipment instructs the UE to transmit five CSI reports on one PUSCH, the UE identifies the reference slot offset corresponding to each CSI report, among which the reference slot offsets of the two CSI reports are equal , assuming that the reference slot offsets of the other three CSI reports are equal, the slot offset of one CSI reference resource is identified based on the maximum of the two identified reference slot offsets. A total of two CSI reference resource slot offsets may be determined based on the determined two reference slot offsets.

It can be easily understood that specifying the slot offsets of a plurality of CSI reference resources for each type of CSI report contributes to further improving the flexibility of the slot offset n _{CQI_ref} of the specified CSI reference resources. .

Optionally, in other embodiments of the present disclosure, the slot offset determination method according to embodiments of the present disclosure further includes reporting CSI computation related capabilities to the network equipment.

wherein the CSI calculation-related capabilities are CSI reporting types supported by the terminal equipment, maximum number of CSI reports supported by the terminal equipment, at least one CSI in different numerologies of CSI reporting types supported by the terminal equipment It includes one or a combination of one or more of the CSI computation time corresponding to the computation complexity level and the identifier of the CSI computation time list supported by the terminal equipment.

Optionally, the CSI computation-related capabilities include CSI information belonging to multiple CCs and CSI computation time at corresponding CSI computation complexity levels that can be updated simultaneously by the terminal equipment, and can be updated simultaneously by the terminal equipment. and a combination of one or more of CSI report combination information for different CSI report types or CSI computation complexity levels and corresponding CSI computation times.

Similarly, by reporting CSI calculation-related capabilities to the network equipment, the network equipment can request the terminal equipment to report CSI based on the actual capabilities of the terminal equipment, and the network equipment sets the CSI request to the terminal equipment. In addition, the terminal equipment can adapt the time for calculating CSI to its own computing power, so that the terminal equipment can report the CSI report to the network equipment at a more appropriate timing. , no waste of time domain resources, no shortage of computing time to report the updated CSI report to the network equipment, and improved efficiency of CSI report feedback by the terminal equipment.

FIG. 2B illustrates a slot offset determination method according to one embodiment of the present disclosure. This method is applied to terminal equipment. As shown in FIG. 2B, the method includes the following steps.

At step 208, identify the CSI computation time at which the terminal will generate the target CSI report.

In one specific embodiment, step 208 specifically includes receiving a CSI calculation time at which the terminal generates a target CSI report, reported from the terminal.

In another specific embodiment, step 208 specifically includes receiving a CSI computation time list identifier supported by said terminal equipment reported from said terminal equipment; identifying a target CSI computation time list that matches the identifier from a CSI computation time list set of , and finding a CSI computation time that matches the target CSI report from the target CSI computation time list.

At step 209, a reference slot offset T is determined based on the CSI calculation time.

Specifically, step 209 includes: determining the ratio of the CSI calculation time and the number of OFDM symbols included in one slot; rounding up the ratio to obtain an integer; specifically including specifying;

Specifically, the reference slot offset T can be determined by Equation 2 below.

where Z is the CSI computation time specified in step 202, _NsymbSlot is the number of OFDM symbols contained in one ^slot ,

indicates rounding up.

In step 210, the reference slot offset T is transmitted to the terminal equipment.

After transmitting the reference slot offset T to the terminal equipment, the terminal equipment can identify the slot offset of the CSI reference resource based on the reference slot offset T received.

Since the slot offset identification method according to the embodiment of the present disclosure can identify the specific value of the reference slot offset T (specifically T1 or T2) based on the CSI calculation time of the CSI report, existing TS38 Complementing that T1 and T2 are not clearly defined in the .214 protocol, it should be noted that LTE systems define constant T1 and T2 values to specify the slot offset n _{CQI_ref} of the CSI reference resource. good too. Therefore, the slot offset n _{CQI_ref} of the CSI reference resource specified in the embodiments of the present disclosure is made more flexible to match the CSI calculation capability of the terminal equipment itself.

FIG. 3 illustrates a slot offset determination method according to one embodiment of the present disclosure. This method is applied to network equipment. As shown in FIG. 3, the method includes the following steps.

In step 301, the CSI calculation time corresponding to the required terminal equipment's aperiodic CSI reporting is determined.

Specifically, in step 301, the CSI computation time corresponding to the aperiodic CSI report is specified by either one of the following two schemes.
Method 1: Determined by the network equipment according to a predetermined CSI calculation time list.
Method 2: Determined by the network equipment based on the CSI calculation-related capabilities reported by the terminal equipment.

Of course, other schemes may be used to identify the CSI computation time corresponding to aperiodic CSI reporting, but the embodiments of the present disclosure are not limited thereto.

Here, the predetermined CSI time list is the CSI time specific list defined according to the conventional protocol, for example, the CSI time specific list defined by the protocol, specifically refer to Table 1 above.

Here, the CSI calculation-related capabilities reported by the terminal equipment are consistent with the embodiments described in FIGS. 1 and 2A, and are not repeated here to avoid duplication.

Note that the CSI reporting required by the network equipment is typically a CSI reporting type that the terminal equipment can support.

In step 302, a slot offset Y for reporting aperiodic CSI reports from the terminal equipment is determined based on the CSI calculation times corresponding to required CSI reports.

Note that the slot offset Y for reporting the aperiodic CSI report from the terminal equipment is usually determined by the slot in which the terminal receives the CSI request information and the slot in which the terminal equipment reports the aperiodic CSI report. is the time interval between

Specifically, taking as an example the CSI-RS associated with the aperiodic CSI-reporting is the aperiodic CSI-RS, Step 302 includes: Including the network equipment specifying the offset X. The time offset X is the time interval between the DCI slot in which the transmission of the aperiodic CSI report request information is triggered and the slot in which the aperiodic CSI-RS is transmitted. Based on the CSI calculation time corresponding to the required CSI reporting and the time offset X, a slot offset Y for reporting the aperiodic CSI from the terminal is identified.

More specifically, based on the CSI calculation time and the time offset X corresponding to the required CSI reporting, identifying the slot offset Y for reporting the aperiodic CSI from the terminal equipment is the required determining the ratio of the CSI calculation time corresponding to a CSI report and the number of OFDM symbols contained in one slot; rounding up the ratio to obtain an integer; determining a slot offset Y for reporting the aperiodic CSI from the terminal device based on .

If the CSI request information received by the terminal indicates that the terminal should report the CSI report to the network equipment after Y slots, the terminal should complete the CSI calculation in less time than the slot offset Y. If yes and cannot be completed, then we know that the updated CSI report cannot be reported to the network equipment.

Therefore, in one specific example, the slot offset Y can be calculated by Equation 3 below.

Corresponding to the contents executed by the network equipment in the embodiments of the present disclosure, on the terminal equipment side, the terminal equipment reports the CSI report by receiving the CSI report request information transmitted from the network equipment via DCI. A slot offset Y can be specified. In addition, if the terminal device cannot find the CSI reference resource based on the slot offset Y of the received CSI report request information, it is too late to calculate new CSI, so the terminal device does not report the CSI report or does not report the CSI report history. can be reported to network equipment.

As such, the network equipment can request CSI reporting from the terminal equipment based on the actual capabilities of the terminal equipment. This not only increases the flexibility of the network equipment to set the CSI requirements to the terminal equipment, but also allows the terminal equipment to adapt the time for calculating the CSI to its own computing power. This allows the terminal device to report the CSI report to the network device at a more appropriate time, without wasting time domain resources, and preventing the lack of computation time to report the updated CSI report to the network device. It is possible to improve the efficiency of the terminal device feeding back the CSI report.

The terminal device 400 according to the embodiment of the present disclosure can refer to the method flow shown in FIG. 1 of the present disclosure, and each unit/module and other operations and/or functions of the terminal device are: Each is for realizing the corresponding flow of the method shown in FIG. 1 and is not repeated here for the sake of brevity of description.

FIG. 5A is a structural diagram of network equipment according to an embodiment of the present disclosure. As shown in FIG. 5A, terminal equipment 500 includes a first receiving module 501 for receiving CSI reporting request information transmitted from network equipment.

Typically, CSI report request information (CSI request) sent from a network device includes information such as the number of CSI reports, the type of each CSI report, the codebook type and CSI reporting bandwidth required to be used by the terminal device. The terminal device can specify the CSI calculation time from these pieces of information.

A first identifying module 502 is used to identify a reference slot offset T based on the CSI reporting request information.

In one particular embodiment, terminal device 500 optionally determines reference slot offset T preset by network equipment prior to identifying reference slot offset T based on said CSI report request information. Further includes a second receiving module for receiving. Then, the first identification module 502 specifically identifies a target CSI report that needs to be reported based on the CSI report request information, and sends a reference slot offset T matching the target CSI report to the network. It is used to specify from among the reference slot offsets T preset by the device.

In another specific embodiment, the first identifying module specifically identifies a CSI calculation time for CSI reporting based on the CSI report request information; and based on the CSI calculation time, a reference slot offset; It is used to identify T.

Specifically, the first identifying module 502 includes a first sub-module for identifying a numerology and a CSI calculation complexity level corresponding to a CSI report, the numerology and the CSI calculation according to the CSI report request information; and a second sub-module for specifying the CSI computation time for the CSI report at the complexity level.
Here, the second sub-module specifically:
determining a CSI computation time for CSI reports at the numerology and the CSI computation complexity level based on the CSI computation-related capabilities of a terminal device;
receiving a CSI calculation time for a CSI report at the numerology and the CSI calculation complexity level previously signaled by a network device;
the numerology and the CSI computation complexity by any one of: identifying a CSI computation time for a CSI report at the numerology and the CSI computation complexity level based on a predetermined CSI computation time list; Used to specify the CSI computation time for CSI reporting at the level.

The predetermined CSI time list is a CSI time specific list defined based on conventional protocols, such as a CSI time specific list defined in the TS38.214 protocol.

In this specific embodiment, the first identifying module 502 is specifically used to identify the reference slot offset T based on the CSI calculation time.

Specifically, the first identifying module 502 specifically identifies the ratio of the CSI calculation time and the number of OFDM symbols included in one slot, rounds up the ratio to obtain an integer, and It is used to specify an integer as the reference slot offset T.

That is, the reference slot offset T can be specified by the following Equation 5.

Equation 5

ここで、Ｚは、ステップＳ２０２で特定されたＣＳＩ計算時間であり、Ｎ_ｓｙｍｂ ^Ｓｌｏｔは、１つのスロットに含まれるＯＦＤＭシンボル数であり、

は、切り上げを示す。

where Z is the CSI calculation time specified in step S202, N _symb ^Slot is the number of OFDM symbols included in one slot,

indicates rounding up.

A second identifying module 503 is used to identify the slot offset of the CSI reference resource based on the reference slot offset T.

Since the terminal device according to the embodiment of the present disclosure can identify the specific value of the reference slot offset T (specifically T1 or T2) based on the CSI report request information, the existing TS38.214 protocol does not clearly define T1 and T2, and may not refer to defining constant T1 and T2 values to specify the slot offset n _{CQI_ref} of the CSI reference resource in the LTE system. Therefore, the slot offset n _{CQI_ref} of the CSI reference resource specified in the embodiments of the present disclosure is made more flexible to match the CSI calculation capability of the terminal equipment itself.

In addition, when the first identification module 502 identifies the CSI calculation time of the CSI report at the numerology and the CSI calculation complexity level based on the CSI calculation related capability of the terminal device, the slot of the identified CSI reference resource The offset n _{CQI_ref} can be matched according to the CSI calculation capability of the terminal device itself, so that the terminal device can timely report the CSI report to the network device without wasting time domain resources and running out of calculation time. It can be seen that the efficiency of feedback of CSI reports by the terminal equipment is improved without the inability to report updated CSI reports to the network equipment.

Optionally, in another embodiment of the present disclosure, the second identifying module 503 specifically indicates by CSI report request information that there are multiple CSI reports, and at the CSI calculation time of the multiple CSI reports, If the number of reference slot offsets T identified based on is plural, the maximum value of the identified plurality of reference slot offsets T is used to identify the slot offset of the CSI reference resource.

Optionally, in another embodiment of the present disclosure, the second identifying module 503 specifically indicates by CSI report request information that there are multiple CSI reports, and at the CSI calculation time of the multiple CSI reports, determining slot offsets for at least two CSI reference resources based on different reference slot offsets T of the determined plurality of reference slot offsets T, if the number of reference slot offsets T determined based on used for

It can be easily understood that specifying time slot offsets of a plurality of CSI reference resources for each type of CSI report contributes to improving the flexibility of time slot offsets of the specified CSI reference resources.

Optionally, in another embodiment of the present disclosure, terminal equipment 500 further includes a UE capability reporting module. The UE capability reporting module, based on the CSI computation-related capability of the terminal device, in identifying the CSI computation time of the CSI report at the numerology and the CSI computation complexity level, and based on the CSI report request information. It is used to report CSI computation related capabilities to network equipment prior to specifying the CSI computation time of the CSI report.

wherein the CSI calculation related capabilities are:
CSI reporting types supported by the terminal equipment;
the maximum number of CSI reports supported by the terminal equipment,
CSI calculation times corresponding to at least one CSI calculation complexity level in different numerologies of CSI reporting types supported by the terminal equipment;
Identifiers of the CSI calculation time list supported by the terminal equipment, or a combination of one or more of them.

Optionally, said CSI computation related capabilities are:
CSI calculation time for CSI information belonging to multiple CCs and corresponding CSI calculation complexity levels that can be updated simultaneously by a terminal device; and
It further includes one or more combinations of CSI report combination information of different CSI report types or CSI calculation complexity levels and corresponding CSI calculation times, which can be simultaneously updated by the terminal equipment.

Similarly, terminal equipment 500 can report CSI computation-related capabilities to network equipment. As such, the network equipment can request CSI reporting from the terminal equipment based on the actual capabilities of the terminal equipment. This not only improves the flexibility of the network device to set the CSI request to the terminal device, but also allows the terminal device to match the time for calculating CSI with its own computing power. This allows the terminal device to report the CSI report to the network device in a more timely manner, without wasting time domain resources, and without running out of computation time to report the updated CSI report to the network device. It is possible to improve the efficiency of the terminal device feeding back the CSI report.

A terminal device 500 according to an embodiment of the present disclosure can refer to the method flow shown in FIG. Each is for realizing the corresponding flow of the method shown in FIG. 2A and is not repeated here for the sake of brevity of description.

FIG. 5B is a structural diagram of network equipment according to an embodiment of the present disclosure. As shown in FIG. 5B, network appliance 504

a fifth identification module 509 for identifying a reference slot offset T based on the CSI calculation time;

Since the network device 504 according to embodiments of the present disclosure can specify a specific value for the reference slot offset T (specifically T1 or T2) based on the CSI calculation time of the CSI report, the existing TS38. H.214 protocol does not explicitly define T1 and T2, and without reference to LTE systems defining constant T1 and T2 values to specify the slot offset n _{CQI_ref} of the CSI reference resource. good. Therefore, the slot offset n _{CQI_ref} of the CSI reference resource specified in the embodiments of the present disclosure is made more flexible to match the CSI calculation capability of the terminal equipment itself.

a slot offset determination module 602 for determining a slot offset Y for reporting aperiodic CSI reports from the terminal based on the CSI calculation times corresponding to required CSI reports.

Specifically, in the computation time determination module 601, the CSI computation time corresponding to the aperiodic CSI report is determined by one of the following two schemes.
Method 1: Determined by the network equipment according to a predetermined CSI calculation time list.
Method 2: Determined by the network equipment based on the CSI calculation-related capabilities reported by the terminal equipment.

Of course, other schemes may be used to identify the CSI computation time corresponding to aperiodic CSI reporting, but the embodiments of the present disclosure are not limited thereto.

Here, the predetermined CSI time list is a CSI time identification list defined based on a conventional protocol, for example, a CSI time identification list defined by the TS38.214 protocol, specifically Table 1 above. refer.

Note that the CSI reporting required by the network equipment is typically a CSI reporting type that the terminal equipment can support.

Note that the slot offset Y for reporting the aperiodic CSI report from the terminal equipment is usually determined by the slot in which the terminal receives the CSI request information and the slot in which the terminal equipment reports the aperiodic CSI report. is the time interval between

Specifically, slot offset identification module 602:
A time offset X of an aperiodic CSI-RS transmission associated with an aperiodic CSI report, wherein the slot of DCI in which the transmission of the aperiodic CSI report request information is triggered and the aperiodic CSI-RS transmission a time interval identification sub-module for identifying said time offset X, which is the time interval with respect to the slot to be executed;
a slot offset Y identification sub-module for identifying a slot offset Y for reporting the aperiodic CSI from the terminal device based on the CSI calculation time and the time offset X corresponding to the required CSI reporting.

More specifically, the slot offset Y identification sub-module identifies the ratio between the CSI calculation time corresponding to the required CSI report and the number of OFDM symbols included in one slot; and based on the integer, the time offset X and the timing advance N, identify a slot offset Y for reporting the aperiodic CSI from the terminal.

If the CSI request information received by the terminal indicates that the terminal should report the CSI report to the network equipment after Y slots, the terminal should complete the CSI calculation in less time than the slot offset Y. If yes and cannot be completed, then we know that the updated CSI report cannot be reported to the network equipment.

Therefore, in one specific embodiment, slot offset Y is calculated by Equation 6 below.

Formula 6

where X is the time offset X, Z is the CSI calculation time specified in step 301, N _symb ^Slot is the number of OFDM symbols contained in a slot,

indicates rounding up, N is the timing advance TA, and the unit of N is OFDM symbols, for example, TA=1.4 symbols.

Since the slot offset n _{CQI_ref} of the CSI reference resource above is also calculated from the ratio value of 'Z/N _symb ^Slot ', in another specific embodiment, the slot offset Y is also calculated by Equation 7 below: be done.

Equation 7

The network device 600 according to the embodiment of the present disclosure sets the slot offset Y at which the terminal device reports the aperiodic CSI report based on the CSI calculation time corresponding to the terminal device's aperiodic CSI report required by the network device. can be specified, so that the slot offset Y at which the terminal equipment reports the aperiodic CSI report specified by the network equipment can be more reasonable, and finally the terminal equipment receives the CSI report request information. After that, the new CSI information can be successfully reported to the network equipment, and the CSI information obtained by the network equipment will be more reflective of the actual channel conditions.

Optionally, in another embodiment of the present disclosure, network appliance 600:
If the CSI calculation time corresponding to the aperiodic CSI report is specified by the network equipment based on the CSI calculation-related capabilities reported by the terminal equipment, then the required terminal equipment's aperiodic CSI report is supported. It further includes a UE capability receiving module for receiving CSI calculation related capabilities reported from the terminal equipment before specifying the CSI calculation time.

wherein the CSI calculation related capabilities are:
CSI reporting types supported by the terminal equipment;
the maximum number of CSI reports supported by the terminal equipment,
CSI computational complexity of at least one CSI computational complexity level in different numerologies of CSI reporting types supported by the terminal equipment; and
Identifiers of the CSI calculation time list supported by the terminal equipment, or a combination of one or more of them.

Optionally, said CSI computation related capabilities are:
CSI calculation time for CSI information belonging to multiple CCs and corresponding CSI calculation complexity levels that can be updated simultaneously by a terminal device; and
It further includes one or more combinations of CSI report combination information of different CSI report types or CSI calculation complexity levels and corresponding CSI calculation times, which can be updated simultaneously by the terminal equipment.

Based on this, network device 600 optionally further includes a configuration module for configuring a terminal device with a CSI computation time identified based on CSI computation-related capabilities reported by the terminal device.

In addition, when specifying the CSI calculation time of the CSI report at the numerology and the CSI calculation complexity level based on the CSI calculation related capabilities of the terminal equipment, the slot offset Y at which the CSI report is reported from the identified terminal equipment The CSI calculation capability of the terminal equipment itself can be more adapted, the terminal equipment can report the CSI report to the network equipment at a more appropriate time, and the time domain resource is not wasted, and the calculation time is insufficient and the update is completed. It can be seen that the efficiency of feedback of CSI reports by the terminal equipment is improved without preventing the CSI reports from being reported to the network equipment.
